Abstract – Structural Analysis is the method to ensure the
safety of the structure. This project “Analysis of A Commercial
Cum Residential Building usingETABS”deals withtheanalysis
and design of a multi-storied commercial cum residential
building(B+G+3) using the software ETABS (Extended Three
Dimensional Analysis Of Building Systems). This software
enables to check the stability of structure under gravity
loading, shear forces and seismic loads. The proposedsiteisin
Pathanamthitta with a plot area of 25 cents. The dead load
and live loads are applied and the design for beams, columns,
slab is obtained. In this project we are considering seismic
load as the lateral load. In this project, limit state method is
adopted for analysis. In this work, an attempt is made
according to Building Bye Laws and design of building is done
as per IS: 456-2000, SP-16 and SP-34 specifications.
Key Words: Structural analysis, ETABS, Seismic load,
Codes used
1. INTRODUCTION
A building is a structure with columns, beams, slab, roof and
walls standing more or less permanently in one place. A
building should be capable to resist all the applied loads
without failure during its intended life for that structural
analysis have to be done. The process of collecting
information and evaluating the conditions of the site for the
purpose of designing and constructing the foundation for a
structure is called the geotechnical site investigation.
Structural engineers are facing the challenges of striving for
most efficient and economical design with accuracy in
solution while ensuring that the final design of a building
and the building must be serviceable for its intended
function over its design life time. Nowadays, various
software packages are available in market for analyzing and
designing practically all types of structures.
High rise buildings are in high demand because of the world
population boomanddevelopmentoftechnologyduring past
decades.Variousstructural formsandconstructionmaterials
were developed along with a diverse assemblage of
structural and non-structural components. The real
performance of the high rise structures depends greatly on
the integrated interaction of structure and non structural
components. This makes the behavior of muilti-storeyed
structures complicated.
In current design practice,thelateral loadresistingsystemof
a high rise building is considered vital to the whole
structure.
For the design of the structure, the dead load, live and
seismic loads are considered. The analysis and design of the
structure is done by using software called as ETABS. In this
project, limit state method is adopted for analysis. The
design is in confirmation with IS 456-2000. The results of
analysis are used to ensure the fitness of structure for use.
1.1 OBJECTIVE
 The project concerned with the analysis & designof
a commercial cum residential building (B+G+3)
consisting of parking facilities,commercial area and
apartments.
 The proposed site was inPathanamthitta witha plot
area of 25 Cents.
 The design was done in accordance with the
provisions of IS Codes.
 The main objective of this projectwastodesignand
analyze a building using ETABS.
 The objective of structural design is to design a
structure that’s stable against overturning, sliding
and buckling.
2. DESIGN PHILOSOPHY
Limit State Method
It is based on the concept as to achieve an acceptable
probability that the structure will not becomeunserviceable
in its life time. Hence this method is based on the philosophy
that the structure should be able to withstand safely the
working load throughout its life span and also satisfy the
serviceability requirement. In the design the following limit
states are examined;

 Limit State of Collapse
It corresponds to the maximum load carrying capacities and
its violation implies failure but do not mean complete
collapse. This limit state has close similarity to: flexure,
compression, shear, and torsion.
 Limit State of Serviceability
It corresponds to the development of excessivedeformation.
This state corresponds to: deflection, cracking & vibration.

5. PROCEDURE IN ETABS
Step 1: Select standard codes and country codes.
Step 2: Generation of grid lines and structures.
At first open ETAB, select new model. A grid system will
appear on the screen in which we enter the dimension
values.
Step 3: Define property.
First define the material property from menu material
properties. Then define each components of the structure
such as columns, beams, slab, wall, footings. In defining
section, add all the data regarding the components size,
shape, reinforcement details cover etc.

Step 4: Assigning property
After defining, assign each section along with the material
property.
Fig -3: Property assigning
Step 5: Define loads
Load combinations are initially introduced into the ETAB
consisting of dead, live, seismic and super imposed load.
Step 6: Assigning load combination
Live load of 4kN to 5kN is generally assigned and dead load
constitutes of floor finish is considered. Since the height of
building is 15m, according to provision of code wind load
can be neglected. As per IS 1893:2002 earthquake response
reduction factor is considered on both X and Y direction.
Step 7: Analysis
After completion of all the above steps then have to analyse
the structure and check for errors.

Step 8: Design
After analysing the structure the designing of the concrete
structure have to be done as per IS 456:2000.
6. SEISMIC ANALYSIS
Seismic analysis is a part of structural analysis. It is the
calculation of the response of a building structure
to earthquakes. Here dynamic analysis is done in this
structure. In thisDynamicanalysisisperformed byResponse
Spectrum Method.

Fig -5: Maximum Story Drift
From IS 1893: 2002(part1), clause 7.11, the storey drift in
any storey due to the minimumspecifieddesignlateral force,
with partial load factor of 1.0, shall not exceed 0.004 times
the storey height. From the above data, it is clear that, story
drift is within the allowable limit; hence the structure is safe
against the seismic forces.
7. RESULT ANALYSIS
Fig -6: Bending Moment and Shear Force Diagram
ETAB provide a powerful graphics along with modeling,
analytical, and design procedures, integrated using a
common database. From the shear or spandrel force
diagram, the amount of deflection occurring at each span of
beam can be known. For beamhavingunsafedesignstrength
with greater moment, overwriting can be done.
8. CONCLUSION
The analysis of commercial cum residential building was
done using ETABS. A stable, economic & aesthetic structure
was designed. Use of software proved to be more efficient in
case of time consumption and accuracy. Details of each and
every member can be obtained using ETABS. The structural
components of this building are found tobe safeinshear and
flexure. Seismic analysis is done with response spectrum.
Beam are designed for Flexure, ETABS gives SFD and BMD
for individual member and whole structure. It suggests the
adequacy of the section as a singlyreinforcedsection,doubly
reinforced section. The analysis of structure was successful
using ETABS software.
